Abstract

The geomorphology of Heard Island-McDonald Island is primarily the product of close interplay between volcanism, glaciation, and vigourous marine processes in a stormy sub-Antarctic environment. The dominant landform is the strato-volcano Big Ben on McDonald Island. Other volcanic landforms include scoria cones, domes, open vertical volcanic conduits, lava flows and lava tubes. On Heard Island, a variety of erosional and depositional glacial landforms is present, including major lateral moraines and extensive hummocky moraines. Integrated study of the volcanic, glacial and coastal sequences offers the possibility of constructing a well-dated record of climate change
